Activated Molecular Sieve Powder is obtained by adding special reagent to the original molecular sieve powder and calcining at high temperature. The obtained molecular sieve activated powder. It has strong activity and can be directly used in production as an adsorbent with selective adsorption, such as mixed dispersion adsorption with materials, it is an amorphous desiccant. It can adsorb impurities such as moisture that affect the quality of the product without changing the physical and chemical properties of the product itself.
CHEMXIN Activated Molecular Sieve Powder has good dispersibility, fast adsorption speed, strong activity, can reduce moisture, eliminate air bubbles, and improve material uniformity and strength.
Less Moisture, big troubles.
The existence of trace moisture has become a problem that plagues polyurethane series products and metal-rich coatings.
Trace amounts of moisture present in typical polyurethane formulations react with isocyanate groups to produce amines and carbon dioxide, which can lead to the formation of air bubbles, affect product pot life and post-cure smoothness and adhesion, and accelerate material aging.
Materials based on metal compound formulations, such as coatings rich in zinc, tin, etc., active zinc and tin elements are easily reacted with moisture, releasing hydrogen, which greatly affects product quality, and more seriously, paint storage containers are prone to Over pressure phenomenon, and may even cause leakage and lead to safety accidents.
Let's check below Polyurethane potting compound, many bubbles, it must be moisture inside.
Therefore, how to remove the moisture?
At present, the solutions for the water content of the products on the market include chemical reaction adding a reactant to decompose the water inside and adding molecular sieve activation powder to carry out a physical reaction to absorb the water inside.
Molecular sieve activation powder can quickly achieve deep removal of water, prevent water from reacting with active components, so as to ensure product quality, prolong storage life, and solve the above problems.
Based on different system requirements, CHEMXIN has developed and produced a variety of products with pore sizes 3A, 4A, 5A and 13X Activated Molecular Sieve Powder, which are suitable for water adsorption in different systems without negatively affecting.
Mixture-Activated Molecular Sieve mixed into the materials.
Filtration-Filter impurities.
Finished-No bubble and moisture inside, smooth surface.
FAQ:
Q: How many Activated Molecular Sieve Powder should we add to the material?
A: It’s about 2%-5%, please test it under your actual situation.
Q: How much water content does in our Activated Molecular Sieve Powder?
A: Less than 1.0%. Full automatic production line and strictly production control help greatly reduces the moisture content of Activated Molecular Sieve Powder.
Q: Do your Activated Molecular Sieve Powder have impurities?
A: No. There will have some iron chippings in old machines, we are the new machines, and will refurbish and inspection the machines in a regularly, thus 0% impurities.
